Data Mining Is Shaping Our World. Are We Ready for It?

Each day, we exchange a mess of content through Facebook, Twitter, blogs, discussion boards and other online forums. What does this digital information reveal about our real selves, and how are companies and other organizations using our data?

In a July cover article titled “The Web Means the End of Forgetting,” the New York Times Magazine explored how the Internet is changing privacy. Recently, the Wall Street Journal reported on Google’s “soul-searching” over the question of how far to go in “profiting from its crown jewels -- the vast trove of data it possesses about people’s activities.”

Rohini Srihari, who teaches classes on Web search and mining and is founder and CEO of Janya Inc., a text analysis/text mining firm, understands the potential of data mining -- and the complicated concerns it raises.

Why is Google’s data trove so valuable?
Srihari: The sheer volume of data that they have is powerful -- there’s so much of it, and it’s so diverse. It reflects the voice of consumers, the voices of citizens, the voices of people across countries. One way they can exploit this information is through usage mining, which is tracking how people are using the Internet. They know what people are querying. Google has access to all sorts of information that marketers would love to get their hands on. When people query a brand, for instance, what are they querying for? Google was able to spot outbreaks of flu-like illnesses before government agencies could, because government agencies rely on traditional reporting, waiting for hospitals to send in statistics, whereas Google relies on queries. They know what people are querying for and where those queries are coming from.
What other companies or organizations are investing in data mining on the Web, and why?

Srihari: Practically everyone. The telecoms, credit card agencies, major retailers, airlines, e-commerce providers like Amazon -- all of these entities are engaged in data mining. One emerging technology is socially targeted advertising. Companies that provide this service analyze the browsing patterns of brand loyalists, identify Internet users with similar browsing patterns, and use that information to target advertising. The success stories of companies attracting new customers through socially targeted advertising are amazing.

What are some interesting challenges that researchers and companies face when mining data on the Web?

Srihari: The No. 1 challenge is balancing privacy with data mining. We’ve come to a stage where we do less than we can for fear of spooking the public. How do you gain enough information to help a retailer without creating a backlash? You don’t want people to feel like you’re invading their privacy. There are technical challenges, like making sense of text with multiple languages or spelling mistakes, but it’s achieving that balance between data mining and privacy that is the No. 1 challenge.

What are some potential public benefits that could come from data mining?
Srihari: Data mining has the potential for making a serious impact on societal problems. Trends emerge quickly on the Web, and that can be used in an advantageous way. Google’s ability to spot outbreaks of flu-like activity is one example. Law enforcement is another. We’ve heard that gang members often post on their Facebook pages what they did, so law enforcement agents frequently go and look at Facebook to glean additional information. In local communities, if the volume of communication or chatter about some topic increases to a certain level -- maybe roads need fixing or there’s a dangerous traffic light -- public officials might take notice.
How might data mining affect the average Internet user?
Srihari: We’re going to see more of this socially targeted advertising, and it might start making people wonder, “How did they know that I was interested in traveling to Peru, or that I was looking to buy this thing?” It’s one thing when you’re doing a Google search and you see some advertising appear on the side. It’s quite another thing when you’re reading the newspaper online, and you suddenly see an ad that’s targeted specifically at you that’s unrelated to the content on the page. As people become more aware of how much their Internet activities reveal, they may become more wary about the way they communicate. We’re going to see more debate about privacy.

The University at Buffalo is a premier research-intensive public university, a flagship institution in the State University of New York system and its largest and most comprehensive campus. UB’s more than 28,000 students pursue their academic interests through more than 300 undergraduate, graduate and professional degree programs. Founded in 1846, the University at Buffalo is a member of the Association of American Universities.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
